Understanding Credits, Passes and Distinctions
- Credit (A1–C6): These grades are widely accepted by Nigerian universities as meeting O’Level credit requirements.
- Pass (D7–E8): Technically a pass according to the examination body, but most universities do not accept them as credits for admission.
- Fail (F9): The subject must usually be retaken if it is required for your intended course.
Understanding O’Level Grades for University Admission
Most Nigerian universities and JAMB require candidates to have at least five credit passes (A1–C6), including English Language and Mathematics, obtained in not more than two sittings. Specific courses often demand credits in particular subjects (for example, Physics and Chemistry for Engineering, or Literature for Law).
Requirements can differ between universities and change from year to year. Always check the current brochure of your preferred institution.
